Sure, but the OP talked about being happy with a 10Mbps link. I think a lot of modern households might find that constraining, even if a 10Gbps link was massive overkill. There are two orders of magnitude in between of course :) Personally I found that going back from a 1Gbps link to ~100Mbps has felt a little sluggish, particularly when downloading games. It's not a huge thing, but being able to get that new game pretty much now was great.
